The System Complete ExperimentsChemistry / BiotechnologyThe system „Complete Experiments: Chemistry“

allows you to set up glass apparatus in an easy

and clear way. The glass equipment can be

clearly distinguished from the dark blue

background of the large-format carrier panel.

Due to the sharp contrast between this back-

ground and the glass equipment, the students

can clearly recognise and comprehend the

experimental set-up. The fastening elements

for the glass equipment are hardly visible. Thus

only the experiment and no distracting support

material catches the eye.

Several holders are available for mounting the

various experimental set-ups. These can be

fitted into the perforations of the matrix panel

wherever they are needed. Thus numerous ex-

perimental arrangements are possible some of

which are shown in this brochure.

The experimental set-ups can remain on the

panel which can then be taken off the frame

and stored in a special rack system. It is thus

possible to prepare several complete experi-

ments (as indicated by the name „Complete

Experiments: Chemistry“) in advance and to

store them for immediate use whenever they

are needed. During class, the experiments

which are no longer needed can be removed

and replaced very quickly.

Mechanics

Resolution of forces on an inclined plane

The angle of the inclined plane can be read off in a direct way using the

magneto-adhesive optical (angular) disc. The marking arrows serve for

showing the direction of the weight, of the down-slope driving force and

of the normal force. It is also possible to draw force arrows of the

correct length onto the board using water-soluble pens thus allowing to

develop the parallelogram of forces.

Restoring force on a displaced pendulum

If a thread pendulum is displaced and released again, it tries to reach

its resting position and starts to swing. In the experiment shown in the

picture the pendulum is held at its maximum deflection by a torsion

dynamometer. The force indicated by this dynamometer corresponds to

the restoring force of the pendulum. Whether this force depends on the

deflection of the pendulum or not can be tested in the course of the

experiment.

Fixed pulley

Has a fixed pulley by means of which a weight is to be lifted got any

influence on the force needed for this purpose?

This question can be answered using a wide range of demonstrative

material such as rulers, arrows and lettering on the board.

Mechanics

Uniformly accelerated motion

The track is fixed on the demonstration board with the aid of two

magneto-adhesive holders. Light barriers serve for recording the motion

of the model car.

The new universal timer 4-4 (13605.99) can be attached to the top of

the board for demonstration purposes.

Horizontal and diagonal motion ofprojection

There is no demonstrative method for showing the horizontal and diago-

nal motion of projection in a better way than by using a continuous

water jet. The discharge vessel contains about 1 litre of water thus

giving the experimenter enough time to explain all aspects of the

motion of projection in the course of the experiment.

It is especially impressive to change the angle of projection while the

water flows out.

Energy transformation during upward &downward runs

A special feature of the PHYWE mechanics equipment for the magnetic

board is the flexible track which allows you to set up completely

unconventional track shapes for the experiments. The experiment here

shows an upward and downward track (rollercoaster) which serves for

demonstrating the transformation of potential energy into kinetic

energy and vice versa. The flexible track can be bent in a wide range of

different shapes.

The outer rim is fitted with a raised border to keep the model car or

little balls, which can also be used for the experiments, on the track.

Experiments using a solar collectorThe clamp on holder no. 02164.00 is attached to the aluminium frame

of the demonstration board to hold a reflector lamp. The absorber

plates of the solar collector no. 02165.00 allow you to study, for

instance, the influence of the colour of the absorber. Large-format

display units for indicating the temperature and time values can be

attached to the board.

The solar collector can also be used to heat water flowing through the

collector. The increase in temperature depends on the volumetric flow

of the water.

Absorption of thermal radiation Utilisation of solar energy

Volumetric expansion of gases Linear expansion of solid bodies

The measurement of the volumetric expansion of gases at constant

pressure can be done using a U-tube manometer with mobile legs. The

heated air volume expands thus displacing the right leg until the water

Experiments on thermal expansionis on the same level in both legs again (p = constant). The volumetric

expansion can be measured with the aid of the measuring scale and

marked by means of coloured arrows.

The measurement concerning the linear expansion of solid bodies can

be carried out using a metal tube which is tightly fixed at one end while

the other end rests on an indicator. When hot steam passes through the

tube, the tube expands. The deflection of the indicator can be marked

with the aid of magneto-adhesive arrows.

Chemistry

� Easy to set-up: in themanual a drawing shows thepositioning of the holdersand the picture shows theassembly of the items.

Chemical fountains

Some gases, such as hydrogen chloride, are extremely soluble in water. 1 liter of water solubilises

approx. 443 liters of hydrogen chloride at 20°C. In a closed flask the gas gets in contact with

water resulting in low pressure which draws more water into the flask. This is the basic principle

of a chemical fountain, an exciting experiment for demonstrating the solubility of gases in water.

In the shown version, the production of the hy-

drogen chloride, the filling and the sputtering of

the fountain flask occur in one and the same

apparatus.

Faraday's law

An electrical current through a solution may

result in conversion of substances. The current

is the driving force of the concurrent redox

reactions.

During electrolysis of water which is made

conductive by the addition of ions, hydrogen is

formed at the cathode and oxygen at the

anode. By separate collection of the gases (e.g.

using the electrolysis apparatus – Hofmann

type) the reaction can be observed in a quanti-

tative way and both the Faraday’s laws can be

derived.

The first law proves that the amount of

substance produced during electrolysis is pro-

portional to the amount of charge which flowed

through the solution.

The second law proves that the electro-

chemical equivalents of elements behave to

each other in the same way as their equivalent

masses (molecular mass divided by the

valency).

Both laws can be derived in demonstrative

experiments using the shown set up.

24

Fused-salt electrolysis

The fused-salt electrolysis of sodium chloride

to produce chlorine and sodium which can be

further processed and turned into caustic soda

solution is an important commercial-scale

process. The experiment shown in the picture

allows demonstration of the important steps of

this process in a simple way. However, as the

melting point of sodium chloride is extremely

high, lead chloride with a significantly lower

melting point is used as the model substance.

The PEM (proton exchange membrane) technology is the

fuel cell type favoured by automobile manufacturers and

the manufacturers of combined heat and power stations.

In the demonstration set-up shown in the picture, hydro-

gen is produced the classic way in a gas generator by the

reaction of hydrochloric acid on zinc. It is then passed

through distilled water for cleaning. Inside the PEM fuel

cell, the hydrogen is converted into water and electrical

energy using oxygen (taken from the air). The electrical

energy thus produced by the fuel cell is used to drive a

small motor.

The advantage of the experimental set-up shown here is

that this way to generate hydrogen does not require an

external power supply (electrolysis) or a pressure gas

container. One can generate as much hydrogen as one

needs and whenever one needs it in a particularly simple

way.

Model experiment on thedesulphurisation of flue gas

At an average, German black coal contains 1 ton of

sulphur in 100 tons of coal. During combustion thereof,

2 tons of sulphur dioxide are formed. Therefore a large

power plant with a power of 700 MW which burns

approx. 200 tons of black coal per hour produces approx.

100 tons of sulphur dioxide each day. Such large

amounts of pollutant cannot be blown into the air, the

flue gas must be desulphurised.

The model experiment shows the chemical processes of

desulphurisation of flue gas in a simplified manner such

as take place in power plants today. The clear and

compact set-up and simplification compared to an

industrial process makes it easy to understand this

procedure.

Gas chromatography

The shown didactical set-up for demon-stration of gas

chromatography in a tempera-ture range up to 100°C

suits well for an introduction to the principles of the gas

chromatographic separation of mixtures of substances.

The stationary phase of the gas separating column can

be easily be self-filled at low costs, e.g. using

dinonylphthalate adhered to diatomaceous earth. Helium

gas is used as a carrier. A NTC temperature probe shows

the thermal conductivity of the separated components of

a mixture as a signal which can be recorded via the

control unit of a plotter or on a PC interface.

The modular set-up allows the identification of every

component which is used in the process in a simple way.

These components are not observable in the commer-

cially used chromatographs due to their compact design.

The separating column and its heating mantel are

manufactured out of glass. So, exactly where the

separation of the mixture happens is completely transpa-

rent.

The amplified signal of the heat conductivity sensor can

be comfortably recorded using an interface like the

shown Cobra3 CHEM-UNIT.

Microbial synthesis of ethanolby means of Zymomonas mobilis

Zymomonas mobilis proved to be much more efficient

than yeast in the synthesis of ethanol.

In this experiment, Zymomonas mobilis is fermented

in a bioreactor. The experimental set-up is quite sim-

ple. The inoculated reactor pot is placed in a hot-

water bath on a magnetic stirrer and a hotplate

assuring temperature control and thorough mixing. It

is not necessary to withdraw consumed medium or to

add fresh medium as this is a static culture also

known as a batch culture.

The samples taken can be submitted to a photometric

determination of the cell density. Apart from that it is

also possible to determine the number of cells in a

counting chamber in order to set up a growth curve.

Chemical or enzymatic tests show the consumption of

glucose and the production of ethanol.

Biotechnology

Biotechnologicalproduction of ethanol

Biotechnological production methods are becoming

increasingly important. Every day, the list of products

produced with the aid of bacteria, yeast or certain cell

cultures gets longer and longer. Production takes

place in so-called bioreactors (fermenters) allowing

control of the mixing, the aeration, the pH-value, the

temperature etc. in a very precise way. However,

these fermenters are too complicated for being used

in class. The bubble bioreactor shown in the picture is

not only very simple but also an optimum, low-cost

solution for experiments in the field of education. To

demonstrate the function of such a reactor, molasses

(sugar production waste product) can be fermented to

ethanol in a so-called batch process.

Bacteria in the service ofmining

In the 1950’s, the importance of certain bacteria for

the extraction of metals out of ores was discovered.

Nowadays, microbial ore leaching of so-called low-

grade ores constitutes more than 10 % of the total

production of copper in the USA alone.

The bioreactor shown in the picture serves to

demonstrate this method of ore leaching (e.g. copper

out of copper ores) with the aid of these bacteria

(Thiobacillus ferrooxidans) in a very simple and

comprehensive way.
